Abstract: An improvement in the functional properties of a brittle substrate such as glass is achieved by application of an aqueous solution of a silane to the surface of the substrate. The solution comprises monomeric materials containing silanols, and incorporates at least one function such as strength, color and radiation modification. The materials of principal interest are silanes with at least one alkoxy group connected to silicon, and preferably having three alkoxy groups. The alkoxy silanes are dissolved in an aqueous solution in concentrations of from 1 to 100% by weight. After application, the coatings are cured. Coated articles are provided with useful characteristics.

Abstract: N-(2,2,6,6-tetraalkyl-4-piperidinyl)amine-hydrazides of dicarboxylic acids contain a light stabilizing group, a heat stabilizing group, a 5-membered lactam ring and a reactive hydrazide functionality in the same molecule. The reactive stabilizers can be prepared by reacting 4-amino-2,2,6,6-tetraalkylpiperidines with dialkyl itaconates followed by hydrazinolysis of the ester group of the intermediate mono ester-amide. The compounds are useful for introducing permanent heat and light stability to coreactive polymers or copolymers. They are also useful in the stabilization of inert polymeric systems against the degradative effects of heat and light when merely mixed with, rather than reacted with, the polymers for which stabilization is sought.
